循环浏览chrome选项卡和关闭页面,具体取决于网址

Question

我希望能够遍历chrome页面上的所有选项卡并关闭任何youtube页面的选项卡.

我做了一些谷歌搜索并找到了下面的代码.有两个(可能更多)问题.首先,我创建了一个WPF应用程序并添加了System.Windows.Automation命名空间(使用visual studio 2015 .net 4.5),但无法识别AutomationElement.

此外,我不确定如何循环选项卡并测试页面是否是youtube页面.

        Process[] procsChrome = Process.GetProcessesByName("chrome");

        if (procsChrome.Length <= 0)
            return null;

        foreach (Process proc in procsChrome)
        {
            // the chrome process must have a window 
            if (proc.MainWindowHandle == IntPtr.Zero)
                continue;

            // to find the tabs we first need to locate something reliable - the 'New Tab' button 
            AutomationElement root = AutomationElement.FromHandle(proc.MainWindowHandle);
            var SearchBar = root.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));
            if (SearchBar != null)
            {
                AutomationPattern[] patterns = SearchBar.GetSupportedPatterns();
                if(patterns.Length > 0)
                {
                    ValuePattern val = (ValuePattern)SearchBar.GetCachedPattern(patterns[0]);
                    if (val.Current.Value.Contains("youtube.com") || val.Current.Value.Contains("youtube.co.uk"))
                        proc.Close();
                }
            }
         }

Answer 1

System.Windows.Automation位于UIAutomationClient.dll中.您是否添加了UIAutomationClient.dll作为项目的参考？

检查值"youtube".

if (SearchBar != null) 
{
    AutomationPattern[] patterns = SearchBar.GetSupportedPatterns();
    if (patterns.Length > 0) 
    {
        ValuePattern val = (ValuePattern)SearchBar.GetCurrentPattern(patterns[0]);
        if(val.Current.Value.Contains("youtube.com"))
            proc.Close();
    }
}

根据你的问题，我写了一个小程序来实现这一点。让我知道它是否有效。

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Threading;
class Program
{

    [DllImport("user32.dll")]
    static extern bool SetForegroundWindow(IntPtr hWnd);

    [DllImport("user32.dll")]
    static extern bool IsIconic(IntPtr hWnd);

    [DllImport("user32.dll")]
    static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

    static void Main()
    {
        Process[] procs = Process.GetProcessesByName("chrome");

        if (procs.Length == 0)
        {
            Console.WriteLine("Google Chrome is not currently open");
            return;
        }

        List<string> titles = new List<string>();

        IntPtr hWnd = IntPtr.Zero;
        int id = 0;
        int numTabs = procs.Length;

        foreach (Process p in procs)
        {
            if (p.MainWindowTitle.Length > 0)
            {
                hWnd = p.MainWindowHandle;
                id = p.Id;
                break;
            }
        }

        bool isMinimized = IsIconic(hWnd);

        if (isMinimized)
        {
            ShowWindow(hWnd, 9); // restore
            Thread.Sleep(100);
        }

        SetForegroundWindow(hWnd);
        SendKeys.SendWait("^1"); // change focus to first tab
        Thread.Sleep(100);

        int next = 1;
        string title;

        while (next <= numTabs)
        {
            try
            {
                title = Process.GetProcessById(id).MainWindowTitle.Replace(" - Google Chrome", "");
                if (title.ToLower().Contains("youtube"))
                {
                    SendKeys.SendWait("^{w}"); // close tab.
                    Thread.Sleep(100);
                }
                next++;
                SendKeys.SendWait("^{TAB}"); // change focus to next tab
                Thread.Sleep(100);
            }
            catch (Exception ex)
            {
                // Chrome internal process, doesn't have tab.

            }               
        }

        if (isMinimized)
        {
            ShowWindow(hWnd, 6); // minimize again
            Thread.Sleep(100);
        }

        hWnd = Process.GetCurrentProcess().MainWindowHandle;
        SetForegroundWindow(hWnd);
        Thread.Sleep(100);

        Console.WriteLine("Closed youtube tabs");

        Console.ReadKey();
    }

}
